River transports are a vital part of the transportation industry, and two of the most common types are BARGES and RAFTS. BARGES are large, flat-bottomed vessels that are typically used to transport goods along rivers and canals. They are usually powered by either a motor or a sail and can carry up to several thousand tons of cargo. RAFTS are smaller vessels that are constructed from logs or other materials and are often used to transport people and goods across rivers. They are usually powered by oars or poles and can carry up to several dozen passengers.
